Wheel and Suspension Facts And Figures

[sliq]

OK! i adjusted my adjustable bilsteins today; took me a good solid 10 minutes to figure out how to do it.

there are 2 collars on each other (they are goldish looking ones, on bilstein, and have square grooves cut into them)

if you wish to lower your car, you will need to turn the lower collar CLOCKWISE first. this will make the collar go down.

then you will need to turn the upper collar clockwise also, to lower the car.

once the car is adjusted to the desirable height, turn the lower collar COUNTER CLOCKWISE towards the upper collar. not too tight, just in case by now you car is at a defectable height and you will need to raise it again in future.

if the collars are stubborn and don't budge, spray some WD40 and use the C spanner (hopefully these came with the shocks) to wrench it in 1/4 turns. otherwise, if they were stubborn like a mofo, i used a flathead screwdriver and hammered it into the grooves to build some momentum.

PS. the car will bed into its height after some driving.

found out an easier way to adjust its height without real use of the c spanner.

rotate the spring

(seriously)

Excellent effort, Mitch - thanks for that.

Just thought I'd add an update here as the link Sliq posted to the thread with Charlie Brown's info doesn't appear to direct correctly now. The thread in question is at viewtopic.php?f=76&t=15398.

(I think I got that right, please correct me if not so!)

Also, a noob question for confirmation.. when refererincing camber and toe settings, is it for each wheel individually or the total of both wheels at the front or rear?

Just thought I'd add that when I weighed one of my CE28N's (15x7 +35) it was actually 4.05 so the stated weights will vary slightly (I saved myself the weight of a couple of wheel nuts )

I had a friend translate the note that comes with all Rays Volk Engineering wheels, just as a point of interest for perspective buyers.



1) This is a test for rim endurance. We have rotated the wheel more than a (100?)* million times, after this, we check to see if there are any changes.

2) This is a test for disk(c)? endurance. After we rotate a wheel more than 200,000 times we will check how it changes.

3) This test is for tire air preservation and strength of disk and joint. We place weights on the tire, and examine whether there is any defects.

4) This test is essentially the same as 3) but we place the weights from different angles.

5) This test is for strength of disk and joint. The tire which was tested in test 4) is connected to a vehicle and rotated. We examine whether it has any defects after more 800,000 rotations.

6) The wheel is analyized in 3 D animation software for strength and design.


Hope this helps some people that purchased Volks/Rays engineering Rims and wondered what it said, and helps make prospective buyers more comfortable

I'm sure its available else-where on the net, but it's nice to have google hits redirect here and have the information available on here for us Keeps of other heathen forums


* I think we have had an issue with the translation here.

Thought you may like the updated wheel weights that includes the later model mx5's.

Can anybody tell me the standard spring rates for a 2000 NB8a?

Ok this is a useful site for working out effective tyre sizes atc. Some one has probably already mentioned it

Very helpful....the car expert in the house wants me to go to 16" rims from 17" so I used it to illustrate a point. He also wants me to do coil overs but can they be made to ride soft enough so a drive to Sth Aust is bearable?

cheers

hold up, so my 62mm ground clearance was the reason I rubbed my tyres out. Too much preload

thanks for the useful information, for reference. righty tighty lefty loosey

A very handy calculator. Amongest other things it allows you to compare your current wheel/tyre combination with another combination. For instance this allows you to see the actual v speedo reading when changing wheels/tyres.
